    I inspected your form in Firefox and Chrome and I recreated problem you mentioned. Seems that this is happening because embed iframe code has fixed height which is processed differently in browsers. Also what I noticed that your HTML is not valid and you have a lot of opening tags which are not closed or closing tags which are not opened.

    You can try fixing your error with changing height by Injecting Custom CSS. To do that inside of your Form Builder select Setup & Embed tab, then click on Preferences, then select Form Styles tab and inside of Inject Custom CSS field at the bottom of existing code paste this code:




    Hope this will help. Let us know if you need further assistance.

    This solves the problem for two of the three pages.  Thank you.  The bottom of the form is still cut off on the page artbusiness.com/servicespecs.html


    Thank you.

    Extend your iframe height in the iframe code, that should help. Or re-embed it with the following iframe embed code.

    <iframe id="JotFormIFrame" onload="window.parent.scrollTo(0,0)" allowtransparency="true" src="https://secure.jotform.us/form/50217462585153" frameborder="0" style="width: 100%; height: 3700px; border: none;" scrolling="no"></iframe>

    The 3700px adjustment in the code solved the problem.  Thank you!
